Fast stamping-press end material collector

ABSTRACT

A fast stamping-press end material collector comprises a tray, one or more diverging chutes, and a moving mechanism, arranged such that the work pieces processed by stamping machine slide to the tray through the diverging chutes, and the moving mechanism moves the tray forward or backward when each work piece slides to the tray for the work pieces collected uniformly in the tray.

FIELD OF THE INVENTION

The present invention is related generally to a stamping machine, andmore particularly, to a fast stamping-press end material collector toreplace human work and to achieve automatic collection of work pieces.

BACKGROUND OF THE INVENTION

In state-of-art metal machining process, the throughput of a faststamping machine achieves as fast as 150 pieces per minute, andtherefore the work pieces after stamped are collected before clean-upprocess by either picking the work pieces up and put them in basket byhand or allowing them to directly fall into basket standstill at the endmaterial exit. However, the former work needs more manpower and thusincreases the cost, while the latter method, even does not waste thatmuch manpower, stacks the work pieces as a pile and causes the workpieces to collide and drag to each other and cause damages.

Therefore, it is desired a fast stamping-press end material collector toreplace human work and to achieve automatic collection of work pieces.

SUMMARY OF THE INVENTION

One object of the present invention is to provide a fast stamping-pressend material collector to replace human work.

Another object of the present invention is to enhance the automation fora stamping machine.

In a fast stamping-press end material collector, according to thepresent invention, the work pieces after processed by stamping machineslides to a tray through a diverging chute, and a moving mechanism movesthe tray after each work piece sliding into the tray such that the nextwork piece will not stack over the previous work piece. As a result, thework pieces will be collected uniformly in the tray.

BRIEF DESCRIPTION OF DRAWINGS

These and other objects, features and advantages of the presentinvention will become apparent to those skilled in the art uponconsideration of the following description of the preferred embodimentsof the present invention taken in conjunction with the accompanyingdrawings, in which:

FIG. 2 shows a side view of the fast stamping-press end materialcollector of FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a top view of a fast stamping-press end material collector100 according to the present invention, and FIG. 2 shows a side view ofthe fast stamping-press end material collector 100. In the collector100, the work pieces after processed by stamping machine are transferredby conveyer belt 102 to entrance 1042 of diverging chute 104, abovewhich gates 106 are arranged to diverge the work pieces entered from theentrance 1042 to eight exits 1044 of the diverging chute 104. Each exit1044 has a feeding hole 108, and when a work piece is thereabove, thefeeding hole 108 is open to allow the work piece to fall in thecollection area 1102 of the tray 110. In this embodiment, the tray 110is placed on platform 1122 of moving mechanism 112 and fixed bypositioning mechanism 1124. The feeding hole 108 is closed right aftereach work piece falls into the tray 110 to prevent the work pieceafterwards from falling into the tray 110 to cause stacking over theprevious one already on the tray 110. Then the moving mechanism 112moves, for example forward or backward, to move the tray 110 such thatthe portion of the collection area 1102 without work piece thereonaligned to the feeding hole 108 for receiving the next work piece. Whenthe tray 110 is full of work pieces, the moving mechanism 112 moves thetray 110 to automatic stacking mechanism 114 to stack the tray 110.After stacking several trays 110 that are full of work pieces therein,the stacked trays 110 are sent to conveyer belt 116 for further cleaningstep. When a tray 110 on the platform 1122 is moved out, the movingmechanism 112 moves the platform 1122 to position below automatic trayprovider 118 where an empty tray 110 is automatically sent to theplatform 1122. While interchanging the trays 110, the work pieces arecontinuously transferred to the diverging chute 104 by the conveyer belt102, but only reach the feeding hole 108. The feeding hole 108 does notopen to allow the work pieces to fall therethrough until the empty tray110 is positioned well thereuner.

While the present invention has been described in conjunction withpreferred embodiments thereof, it is evident that many alternatives,modifications and variations will be apparent to those skilled in theart. Accordingly, it is intended to embrace all such alternatives,modifications and variations that fall within the spirit and scopethereof as set forth in the appended claims.

1. A fast stamping-press end material collector comprising: a tray; at least one diverging chute for work pieces to slide to the tray; and a moving mechanism for moving the tray to collect the work pieces.
 2. The collector of claim 1, further comprising a conveyer belt for feeding the work pieces into the at least one diverging chute.
 3. The collector of claim 1, wherein each the diverging chute has an entrance and a plurality of exits.
 4. The collector of claim 3, wherein each the diverging chute has a gate disposed thereabove for diverging the work pieces that enters into the diverging chute.
 5. The collector of claim 3, wherein each the exit has a feeding hole for the work pieces to fall into the tray.
 6. The collector of claim 1, wherein the moving mechanism comprises: a platform for placing the tray; and a positioning mechanism for locating the tray on the platform.
